AS A DISCLAIMER, THIS PRODUCT IS $20 AND I AM NOT BE GOING TO RATE IT BETTER BECAUSE OF IT’S PRICE TAG.
To begin, this sub is pretty good at frequencies above 35 cycles. Lower than that will make tapping sounds. (not excursion sounds) Just the sub is too fast to do it. THE BUILDING INSTRUCTIONS ARE TERRIBLE! I HAD TO FIGURE OUT MYSELF and even then I did not know if the .9 sq feet was right. I think I covered everything negative, so here are the pros.
It moves quite a bit, even at 3 hz.
The magnet is decently powerful
The surround doesn’t produce much sound
IT LOOKS FREAKING DOPE (in my opinion.
For the price that it is, I would buy another if mine broke in a few weeks.
